Choosing a Sintering Company: You’re A-Z Guide


So you’ve settled on sintering as the mode of manufacturing your next sintered plastic? The next thing is to choose the right company to transform your dreams into reality. The sintering company you choose must be able to direct the process successfully from the conceptualization stage to a finished product with minimum waste, high precision, and cost-effectiveness. To realize the highest-quality factory-grade pe filter, keep in mind the following when choosing a sintering company.

Design Considerations

When you have a clear concept at the beginning, you are sure that each step in the process of production will go efficiently and smoothly. Simplifying geometry and minimizing the parts early on greatly increases your ROI. That’s why it is critical to ensure that you explain the design elements to your chosen sintered plastic manufacturer clearly and as early as possible.

Production Volume

Sintered plastic and PE filter manufacturers that produce low to moderate volumes produce parts that don’t exceed 10,000 in number. This is the recommended option for people who want to produce a prototype quickly or those that require applications that don’t need a large number of parts.

But if you have a large number of jobs, say those running above 750,000 units, your best option would be to choose a high volume sintering company.

One-stop & Full Service

When planning to buy a pe filter or just looking for someone to help you with the latest invention, choose a company that guarantees concept-to-finish manufacturing. By consulting your manufacturer early in the concept and design stages of your job, they can work with you to create the perfect product that gives you timing efficiencies and value cost.

Specification Compliance

One of the best ways to avoid compromises is to choose a sintering company that can suggest only appropriate design modifications necessary to improve your finished sintered plastic. A good company is one that enables you to rely on their knowledge of new technologies and expertise to save time and money in the whole manufacturing process. That means from the design stage, development, and finally production of your plastic products.

Quality Standards

Quality is the most important thing when it comes to the manufacture of sintered plastics. So, how do you ensure that the company you have chosen guarantees the best quality products? Below are some of the questions to ask them to gauge the level of quality of your end product that you will get:

  • Is the company ISO-certified and compliant?
  • Does it ensure that every part passes strict inspection and meets the highest safety and quality standards?
  • Is the manufacturer recognized in the industry? Is there any award it has won for exemplary performance?
  • What kind of machines does the manufacturer have? Are they efficient and high-quality?
  • Does it have updated engineering and software?
  • Who else has the manufacturer worked with?

The Time Factor

Time taken from concept to a finished product varies depending on the kind and size of the project. It’s critical to maintain clear communication with everyone involved in the project at all stages. If you have any time limits, make sure you discuss this with the manufacturer from the start. Also, make sure you factor in potential delays that may happen in design, manufacturing, and shopping.

Sintering Vs. Melting

Most people easily assume that sintering and melting are similar but nothing can be further from the truth.

Melting gets the plastic material hot enough to change it from solid form to liquid form. But sintering involves a highly controlled heating process that reaches just below the melting point of the material in the furnace. It gives you the improved properties of the plastic you want but doesn’t melt it. One of the main advantages of sintering is that you can make parts easily out of metals that have high melting points. When done right, sintering can achieve a lot, including:

  • It eliminates lubricants found in the compacted powder
  • It reduces the oxygen amount on the surface of the material
  • It develops sintered necks between particles, which further reduces pores and increases strength
  • It can fully or partially diffuses other elements like copper, nickel, graphite

High-Temperature Sintering

For sintering to be said to be high-temperature, it must take place at about 100-250 °F hotter than the conventional sintering temperature. High-temperature sintering also tends to be more expensive compared to conventional sintering. That is because you will be paying extra for the manufacturer’s equipment.

But the extra cost is worth it because it can produce powdered material that you cannot get any other way. According to one study, high temperature sintered plastic is improved in the following ways:

  • It has increased tensile strength by up to 30%
  • There is also increased bending fatigue of about 15%
  • Impact energy also increases by 50%

While the sample size was small, there is no denying the impressive nature of the findings. However, high-temperature sintering has a few pitfalls:

The cost of high-temperature sintering furnaces is a lot higher than conventional furnaces. This cost is then passed on to the customer.

Also, parts sintered at high temperatures shrink more. Your manufacturer must plan accordingly bearing this in mind.


Sintered plastic filters like PE filter, PVDF, and PTFE filters have a wide range of applications in the pharmaceutical, textile, chemical, petroleum, machinery, wastewater treatment, and food industries.

To get the best out of your plastic, it is critical to choose the right sintering company. Ideally, you want someone that has a lot of expertise and knowledge in the sector. This means they can advise you on how to cut costs and improve efficiency. You also want a sintering manufacturing company that is fully compliant with the regulations of your particular state. And while looking for a sintered plastic manufacturer, do not forget to emphasize quality. Lastly, consider the time you need your PE filter and other sintering products. Talk with the manufacturer early on and let them know if you have any time constraints.
